● If the CRU Fault LED is on, a fault condition is detected.
○ Restart this IOM using the PowerVault Manager or CLI.
○ If the restart does not resolve the fault, remove the IOM and reinsert it.
● If the previous actions do not resolve the fault, contact your supplier for assistance. IOM replacement may be necessary.
Troubleshooting 2U enclosures
Common problems that may occur with your 2U enclosure system.
The Module Fault LED on the Ops panel, described in Ops panel LEDs—2U enclosure front panel on page 71, lights amber to
indicate a fault for the problems listed in the following table:
NOTE: All alarms also report through SES.
Table 23. Troubleshooting 2U alarm conditions
Status Severity Alarm
PCM alert – loss of DC power from a single PCM Fault – loss of redundancy S1
PCM fan fail Fault – loss of redundancy S1
SBB module detected PCM fault Fault S1
PCM removed Configuration error None
Enclosure configuration error (VPD) Fault – critical S1
Low warning temperature alert Warning S1
High warning temperature alert Warning S1
Over-temperature alarm Fault – critical S4
I
2
C bus failure Fault – loss of redundancy S1
Ops panel communication error (I
2
C) Fault – critical S1
RAID error Fault – critical S1
SBB interface module fault Fault – critical S1
SBB interface module removed Warning None
Drive power control fault Warning – no loss of disk power S1
Drive power control fault Fault – critical – loss of disk power S1
Drive removed Warning None
Insufficient power available Warning None
For details about replacing modules, see the Dell EMC PowerVault ME4 Series Storage System Owner’s Manual.
NOTE:
Use the PowerVault Manager to monitor the storage system event logs for information about enclosure-related
events, and to determine any necessary recommended actions.
Table 24. Troubleshooting PCM faults
Symptom Cause Recommended action
Ops panel Module Fault LED is amber
1
Any power fault Verify that AC mains connections to
PCM are live
Fan Fail LED is illuminated on PCM
2
Fan failure Replace PCM
1. See 2U enclosure Ops panel on page 71 for visual reference of Ops panel LEDs.
2. See 2U PCM LEDs (580 W) on page 75 for visual reference of PCM LEDs.
The storage enclosure uses extensive thermal monitoring and takes several actions to ensure that component temperatures are
kept low, and to also minimize acoustic noise. Air flow is from the front to back of the enclosure.
